Gentle trades Defense for Sp. Defense. Losing physical bulk is rough for a wall, so this only works on Pokemon that already have high Defense or rarely take physical hits. In Legends: Z-A, You'll see it on Chesnaught, Altaria, Glalie among others. Defensive Tera types pair well with Gentle. Dropping a weakness and gaining Sp. Defense makes walls much harder to break.

Gentle raises Sp. Defense by 10% and lowers Defense by 10%. Specially defensive Pokemon balancing both defense stats. 8 Pokemon competitively run this nature.

Is Gentle a good nature for competitive Pokemon?
Yes. It fills a solid niche for defensive builds. You'll see Gentle on dedicated Sp. Defense-focused builds across most tiers and formats.
How do I get a Gentle nature Pokemon?
Three options: (1) Synchronize lead forces wild Pokemon to match your lead's nature. (2) Everstone breeding passes the nature 100% of the time since Gen 5. (3) a Gentle Mint changes the stat effects after the fact. Mints don't change the nature name, just the stat modifiers.
Should I use Gentle or Calm?
It depends on what your team needs. Gentle is the mixed special tank option. Calm is the dedicated special wall option. Most of the time, your Pokemon's moveset and role make the decision obvious.
